WISCONSIN, A CORPORATION OF WISCON- MUSICAL-INSTRUMEN T ELEVATOR.

Application led May 10, 1924. Serial No. 712,312.

To all whom t may concern.'

Be it known that I, FLORIAN F. MANOR, a citizen of the United States, and resident of Oshkosh, in the county of Winnebago and State of l/Visconsin, have invented new and useful Improvements in Musical-Instrument Elevators, of which the following is a description, reference being had to the accompanying drawings, which are a part of this specification. y

rThis invention relates to improvements in musical instrument elevators.

It is now customary to provide the orchestras of moving picture theaters and other places of amusement, with organs, and it is also customary to have the different musicians give solos, and in doing so they usually stand while playing to permit the spot light to shine on them so that the audience can clearly see the soloist while playing. As the organist sits down to play the organ, means have been provided for raising the instrument and the player upwardly to the height desired to be plainly seen while playing the solo. Heretofore, this has been done by providing a pit beneath the platform, supporting the organ and the player, of suliicient depth to receive the elevating mechanism and driving means. The lioor of theaters, usually at street level, incline downwardly toward the stage and the orchestra is usually located at the lowest point and which point is so far below the street level as to negative forming a pit beneath the orchestra floor due to sewer and other conduits being located just beneath the floor.

It is one of the objects of the present invention to overcome the before mentioned diiiiculties and provide a musical instrument elevator which may be mounted on the sur face of the floor with all of the elevating mechanism thereabove.

A further object of the invention is to provide a musical instrument elevator in which the elevating means is not visible while the parts are in their lower position.

A further object of the invention is to provide a musical instrument elevator in which the elevator is automatically positively maintained in any position of elevation.

A further object of the invention is to provide a musical instrument elevator inv which Athe standards for supporting the platform of the elevator in its upper position are hidden from view when the platform is in its lower position.

A further object of the invention isA to rovide a musical instrument elevator which 1s of simple construction, is strong and durable, and is well adapted for the purpose desired.

With the above and other objects in view, the invention consists of the improved musi" cal instrument elevator and its parts and combinations as set forth in the claims, and all equivalents thereof.

In the accompanying drawings in whichy the same reference characters indicate thc same parts in all ofthe views.

Fig. 1 is avertical sectional view taken on line 1-1 of Fig-3; l

Fig. 2 is a vertical sectional detail view taken on a larger scale;

Fig. 3 is a'plan view thereof, with parts removed; and

Fig. 4 is a side view on a smaller scale of the complete elevator showing an organ and seat mounted thereon.

Referring to the drawings, the numeral 8 indicates the floor line upon which. is mounted a rectangular frame 9 prefer-ably formed of metal approximately filled with cement or other material 10 to form a firm foundation. Socket members 11 are embedded in the four corner portions of the material and threaded standards 12 and 12 mounted therein extend upwardly therev` form. A platform 13 of about the same size as the frame 9 and through the corner portions of which the standards 12 and 12 ex tend, is positioned above the frame 9. Nuts 14 threaded on said standards have ball bearing connections 15 with and the platform is supported on the nuts so that when the nuts are turned the platform will be raised or lowered. Said nuts are formed with integral sprocket wheels 16 which are engaged by an endless sprocket chain 17 which passes around all of the sprocket wheels. The nut engaged by the shaft 12' is provided with a worm wheel 18 which is in mesh with a worm 19 mounted on the shaft vof an electric motor 20. Said motor is carried by the platform 13 and the threaded shafts are turned thereby. All of theA standards 12 are formed with right hand threads, andthe respective nuts 1 4 are correspondingly threaded to cause all nuts to move in an up or down direction when turned by the shafts l2 and l2.

To hide the standards from view, tubular posts 22 are mounted on the platform and eXtenf'l over the standards, as clearly shown in Fig. 1, so that all portions of the standards which project above the platform will be hid and the posts in connection with the ropes 23 (only one being, shown), will have the appearance of a guard or enclosure for the organ 2l., the foot pedal case 25 and the bench 25 positioned on the platform Electric wire cables extend from th motor and the organ, preferably7 an electr-i to a source of power supply and to Ihe organ pipe mechanism (not shown) respectively, as now in use. rllhe current to the motor may be controlled in any manner desired.v

From the foregoing description, it v ill be seen that the musical instrument elevator may be mounted in a very easy manner upon a flat surface with all the operating mechanism out of view of the audience of the theater in which the elevator is installe Furthermore, the use of the threaded rards and nuts for raising and lowering74 the platform provides for automatically locking the platform inradjusted position, as the nuts will maintain their adjusted position under load.

What l claim as my invention is:

l. musical instrument elevator, comprising a support, threaded standards eX- tending upwar lly therefrom, nuts threaded on said standards, a vertically movable platform mounttd on sz id nuts, there being a relative movement between the nuts and the standards to raise and lower the platform, means carried by the platforn'i and moving,` therewith for enclosing` from view the portions of the standards above thc platform, and means for causing' said relative movement. i

El. A musical instrument elevator, com prisinp a support adapted to be mounted.
